The disc screw extruder employs a free-floating operating member that is so constructed as to attain substantially stable axial positions within the extruder chamber. The disc component cooperates with confronting surfaces to define inner and outer throat zones, extending along the lead-in and lead-out sections of the disc component, the thicknesses of the flow paths through both of the throat zones decreasing in the outward direction of the extruder.
